Core Material Selection Logic
High-Purity Copper Base for Conductivity
The contact part of the Copper Cap Contact for Electric Vehicle Fuse adopts high-purity electrolytic copper, which boasts excellent electrical and thermal conductivity. This material choice directly addresses the need for stable current transmission in low-current EV fuse systems, minimizing energy loss during operation. Its inherent durability also ensures resistance to wear under frequent use, aligning with the long service life requirements of EV components.
Flame-Retardant Insulation Cap Material
The iCopper Cap Contact for Eaton Bussmann Series EV Fuses is made of flame-retardant engineering plastic that meets strict high-temperature resistance and voltage breakdown standards. This material is specifically selected to withstand the harsh temperature fluctuations in EV engine compartments, preventing insulation failure and short circuits. It complies with automotive-grade safety norms, providing an additional layer of protection for high-voltage electrical systems.
Protective Plating for Longevity
The Copper Cap Contact for Semiconductor Fuses features a specialized plating process on the contact surface, combining enhanced conductivity with corrosion resistance. This plating effectively shields the copper base from oxidation and arc erosion, extending the component's lifespan even in high-frequency on-off cycles. The plating adhesion is optimized through rigorous process control, avoiding peeling issues during long-term use.
Process Design Advantages
| Integrated Injection Molding for Structural Stability | The assembly of the contact and insulation cap utilizes integrated injection molding technology, eliminating gaps between components. This design enhances the overall sealing performance and insulation reliability of the Cap and Contact for EV Charging Fuse, preventing dust or moisture intrusion that could affect electrical performance. It also simplifies the assembly process for EV fuse manufacturers, improving production efficiency. |
| Precision Stamping for Contact Consistency | The contact surface undergoes precision stamping to ensure uniform contact area across all units. Consistent contact dimensions reduce resistance variations between individual Cap and Contact for Fast Acting EV Fuse components, guaranteeing stable performance in batch applications. This precision manufacturing process meets the strict tolerance requirements of EV electrical systems. |
| Roll Plating with Post-Treatment for Uniformity | The plating process employs roll plating combined with professional post-treatment, ensuring even coverage of the contact surface. This technology ensures that every part of the Cap and Contact for Battery Pack Fuse receives consistent plating thickness, avoiding weak points in conductivity or corrosion resistance. The post-treatment process further enhances plating adhesion, maintaining performance integrity under extreme conditions. |
